FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Industrial
Safety and Chemical Hazards Sectional Committee had been approved by the Chemical Division Council.

Hydrofluorocarbons (HFCs) are categories of synthetic chemicals that are being used as alternatives to the ozone
depleting substances (ODS), which are being phased out under the Montreal Protocol and Clean Air Act
amendment of 1990. Because HFCs do not directly deplete the stratospheric ozone layer, they are not controlled
by Montreal Protocol.

These compounds, however, along with sulfiir hexafluoride are potent greenhouse gases. In addition to having
high global warming potentials, many HFC's have extremely long atmospheric life times, resulting in their essentially
irreversible accumulation in atmosphere.

HFC- 134a is an ozone friendly CFC substitute. The t)zone layer in the stratosphere which protects the earth from
ultraviolet radiation from the Sun is getting depleted by various chemicals/substances released in the atmosphere
including chlorofluoro carbons (CFC) used in several industries such as refrigeration, air conditioning, electronics,
foams etc. Montreal Protocol to which India became a signatory in 1992, prohibits the use of CFCs beyond the
year 2010, HFC- 134a is one of the recommended CFC substitute in refrigeration, air conditioning and aerosol
Industries and is a much preferred one for several technical, economic and safety reasons.

There is no standard on this subject published by ISO. This standard has been prepared indigenously based on the
available data and information. In preparation of this code considerable assistance has been derived from the

4.3 Chemical Properties

4.3.1 HFC-134a vapours will decompose when
exposed to high temperature from flames or
electric resistance heaters. Decomposition may
produce toxic and irritating compounds, such as
hydrogen fluoride. The pungent orders will irritate the
nose and throat and generally force people to evacuate
the area. Therefore, it is important to prevent
decomposition by avoiding exposure to high
temperatures.

4.3.2 HFC- 134a / Poly alkylene glycol (PAG) and
HFC- 134a / Polyol ester (POE) solutions have
acceptable chemical stability. HFC- 134a molecule is
as chemically stable as CFC-12. HFC-134a and
CFC-12 are chemically compatible with each other,
this means they do not react with each other to
form other compounds. However, when the two
materials are mixed together, they form azeotrope,
which is difficult to separate. These mixtures can not
be separated in an on-site re-cycle machine or in the
typical facilities of an offsite reclaimer. Mixtures of
HFC- 1 34a and CFC- 1 2 will usually have to be disposed
of by incineration.

4.3.3 HFC- 134a is compatible with steel, copper,
aluminium and brass.

4.3.4 Incompatibility

Finely divided metals, magnesium and alloys
containing 2 percent magnesium. It can react violently
in contact with alkali or alkali earth metals such as
Na, K, or Ba.

4.4 Fire and Explosion Properties

4.4.1 Auto Ignition Temperature^ 770°C

4.4.2 Flammability

HFC- 134a is non-flammable at ambient temperature
and atmospheric pressure. However, it may be
combustible at pressures as low as 5.5 psig at MTC,
When mixed with air at concentrations generally
greater than 60- vol. percent air.

4.5 Corrosion Properties

Not-corrosive.

5 TOXICINFORMATION AND HEALTH

EFFECTS

5.1 Toxicity

HFC- 1 3 4a has very low acute and subchronic inhalation
toxicity and is not genotoxic.

5.2 Routes of Entry
Inhalation, skins and eye contact.

5.3 Health Effects

5.3.1 Inhalation

HFC- 134a poses no acute or chronic hazard when
exposures are maintained below recommended
acceptable exposure limits (AEL) of 1 000 ppm on
8 or 12 hour time-weighted average (TWA) established
by AIHA.

NOTE — AEL is an airborne inhalation exposure limit that
specifies time-weighted average concentrations to which nearly
all workers may be repeatedly exposed without adverse effects.

5.3.2 Asphyxiation

Inhaling high concentrations of HFC- 1 34a vapour may
cause temporary nervous system depression with
anesthetic effects such as dizziness, headache,
confusion and loss of consciousness. It can act as
asphyxiant by limiting available oxygen. Higher
exposures to vapours may cause temporary alteration
of the heart's electrical activity with irregular pulse,
palpitation or inadequate circulation. Inhaling higher
concentrations of HFC- 134a vapour may cause cardiac
irregularities and possibly cardiac arrest.

5.3.3 Skin and Eye Contact

At room temperature, HFC- 134a vapours have little
or no effect on the skin. However, in liquid form, HFC-
134a can freeze skin or eyes on contact causing
frostbite.

6 PERSONAL PROTECTIVE EQUIPMENT

6.1 General

Personal protective equipment is not an adequate
substitute for good, safe working conditions. Adequate
ventilation and intelligent conduct on the part of
employees is essential. One should keep firmly in mind
that personal protective equipment protects only the
person wearing it, and other unprotected workers in
the area may be exposed to danger.

6.2 Non-respiratory Equipment

Personal protecting equipment should include non-
respiratory equipment like splash proof safety goggles
and face shield when working with liquid for eye
protection. Where exposure to cold equipment vapours
or liquid may occur, employees should wear special
clothing designed to prevent the freezing of body

IS 15548 : 2005

tissues. All protective clothing ( suits, shirts witJ|if^
sleeves, insulated gloves) should be clean;-: availabjj;^-
each day, and put on before work. Trousers should be
worn outside boots or overhigh top shoes to shed
spilled liquid.

6.3 Respiratory Equipment

If a large release of HFC- 134a vapour occurs, such as
from a large spill or leak, the vapours may concentrate
near the floor or low spots and displace the oxygen
available for breathing, causing suffocation. An
approved self contained breathing apparatus with a full
face piece operated in positive pressure mode should
be used when entering tanks and other areas where
vapours might exist.

7 STORAGE, HANDLING, LABELLING AND
TRANSPORTATION

7.1 Storage

7.1.1 General Precautions

7.1.1.1 HFC- 1 3 4a must be stored to avoid contact with
heat, flames, sparks and air.

7.1.1.2 Vessels, containers, transfer lines, pumps and
other equipment should not be exposed to high
temperature sources (such as welding, brazing and open
flame) until they have been thoroughly cleaned and
found free of vapours. Any maintenance job on such
equipment should be done under the variety of safety
work.

7. 1 . 1 .3 Only non-sparking tools and equipment should
be used while opening and closing containers of
HFC- 134a.

7.1.1.4 The building shall have good low and high
level natural ventilation. In areas where natural
ventilation is not possible, forced ventilation
equipment should be installed.

7.1.2 Bulk Storage

7.1.2.1 The storage tanks shall be designed as per
standard code.

7.1.2.2 Storage tanks should be equipped with pressure
gauge, liquid level gauge, safety release valves and
excess flow valves.

7.1.2.3 Storage tanks should normally be evacuated at
the start of filling, and should never be filled while under
positive air pressure.

7.1.2.4 Tank pressure should never be allowed to
exceed 300 psig when filling with HFC- 134a. Relief
devices on the tanks usually prevents this.

7.1.2.5 Tank pressures should be monitored routinely.

7.1.2.6 Air lines should never be connected to storage
tanks.

Id 3 Storage of Cylinders

7.1.3Ti The Cylinders of HFC-134a should be kept
out of direct sunlight, particularly in warm weather.
HFC- 134a expands significantly when heated, thereby
reducing the amount of vapour space left in the cylinder.
Once the cylinder becomes liquid full, any further rise
in temperature can cause the cylinder to burst, resulting
in serious personal injury.

7.1.3.2 Never allow the cylinders to get warmer than
52 T,

7.1.3.3 Cylinders should always be raised above dirt
or damp floors to prevent rusting.

7.1.3.4 The storage area should be away from corrosive
chemicals or fiimes to avoid damaging effects on the
cylinder and threaded area of the valve. The cylinders
of HFC- 134a should be kept in cool, dry and properly
ventilated areas.

7.2 Handling

7.2.1 General

7.2.1.1 HFC-134a should be handled wearing an
approved self contained breathing apparatus, chemical
resistance gloves and safety goggles and other
protective clothing {see 6).

7.2.2 Handling of Cylinders

1.22 A Before filling the cylinder with HFC- 134a,
check and confirm its validity. It shall have valid test
certificate from the concerned authorities.

7.2.2.2 Cylinders should never be subjected to rough
handling or to abnormal mechanical shock such as
dropping, bumping, dragging or sliding. They should
be kept in vertical position.

7.2.2.3 Lifting magnet or sling ( rope or chain ) which
may produce sparks should not be used.

7.2.2.4 While handling by crane or derrick, a safe
platform or cradle should be used.

7.2.2.5 Cylinders of HFC- 134a whether empty or filled
should not be used as rollers, supports or for any
purpose other than to carry HFC- 134a.

7.2.2.6 Protect cylinders from any object that will
result in abrasion in the surface of the metal.

7.2.2.7 Never tamper with the safety devices in the
valves.

7.2.2.8 Use only standard colour code for HFC- 134a
cylinders,

7.2.2.9 Before evacuating cylinders, any remaining
refrigerant should be removed by a recovery system.

7.2.2.10 Vacuum pump discharge lines should be free

IS 15548 : 2005

of restrictions that could increase discharge pressures
above 15 psig and result in the formation of
combustible mixtures.

7.2.2. 1 1 Cylinders should normally be evacuated at the
start of filling, and should never be filled while under
positive pressure.

7.2.2.12 Filled cylinders should periodically be
analyzed for air.

7.2.2.13 Empty cylinders should be stored separately
from filled cylinders and fasten empty tag on cylinders
immediately upon emptying.

or prevent leaks.

8.1.2 If spills or leaks of HFC- 1 34a occur, only properly
protected personnel should remain in the area and entry
to others should be prohibited.

8.1.3 Every organisation handling HFC-i34a must
form Emergency Response Team which is available
round the clock. Spills or leaks should be handled by
Emergency Response Team specifically trained to
handle emergency situations.

8.1.4 In case of major spill or leak, the area should be
evacuated immediately. Vapours may concentrate near
the floor, displacing available oxygen.

8.1.5 The area of leak must be ventilated using blowers
or fans to circulate the air at floor level.

IS 15548 : 2005

8.1.6 Use self contained breathing apparatus while
going to close valves or repair source of leak.

8.1.7 Avoid open flames near spillage.

8.1.8 If source of leak is a cylinder and the leak can
not be stopped in place, remove the leaking cylinder to
a safe place in the open air and repair leak.

8.1.9 Prevent liquid from entering sewers, sumps or
pit areas, since vapour can create suffocating
atmosphere. Capture material for recycle or destruction
if equipment is available.

8.2 Leak Detection

8.2.1 Leak detection is important for refrigerant
conservation, equipment protection and performance,
reduction of emissions and protection of those coming
in contact with the system.

8.2.2 No leak testing should be performed with HFC-
134a and air in the system. HFC- 134a may be safely
pressured with dry nitrogen.

8.2.3 Leak detectors may be used for pin pointing
specific leaks or for monitoring an entire room on a
continuous basis.

8.2.4 There are two types of leak detectors, leak
pinpointers and area monitors. Before purchasing either
type, several equipment factors should be considered,
including detection limits, sensitivity and selectivity.
Fluorescent dyes compatible with lubricant and HFC-
134a can also be added to a system for leak detection.

8.3 Waste Disposal

Disposal refers to the destruction of used HFC- 134a.
Disposal may only be necessary when HFC- 134a has
become badly contaminated with other products and
no longer meets the acceptance specifications of
reclaimers. Be sure to check the qualifications of any
firm before sending them used HFC- 134a.

9 RECOVERY, RECLAMATION AND
RECYCLING

9.1 Recovery

9.1.1 Recovery and re-use of HFC-134a is important
